Description

  The present invention relates to an erroneous operation preventing apparatus for preventing an operation unit from being erroneously operated and an electronic apparatus using the same.

  Conventionally, a prior art for preventing the lid of an electronic device from opening unintentionally is known (see, for example, Patent Document 1). In this prior art, the first lock member can be moved between the closed position and the open position while the lid of the battery built in the electronic device is locked in the closed state by the first lock member, and the first lock member is closed. If it is in the position, the lid is locked and does not open, and when the first lock member moves to the open position, the lock is released and the lid opens.

  In addition, the prior art further restricts the movement of the first lock member from the closed position to the open position by the restricting member, and if the restricting member is not switched to the retracted position by the second lock member, the first lock member A structure is employed in which the member does not move to the open position. Thereby, it can be considered that the first lock member is inadvertently operated in a state where the lid is closed, and the lock is released unintentionally and the lid can be prevented from opening.

JP 2011-191748 A

  In the above-described prior art, when the first lock member is moved to the open position, the lid is unlocked. However, in order to move the first lock member to the open position, another second lock member is moved and regulated. It is necessary to switch the member to the retracted position, and it is considered that a so-called double lock is applied to the lid. Thus, if the opening of the lid is double-locked, it is useful for preventing an erroneous operation such that the user accidentally takes out the battery while using the electronic device.

  However, if the second lock member is still switched to the release position in the first place, no restriction is applied to the operation of the first lock member at that time, so there is no way to prevent inadvertent operation as usual. As a result, the first lock member can be easily moved to the open position, and as a result, the lid is easily opened, resulting in an erroneous operation in which the user accidentally takes out the battery.

  Moreover, in the prior art, since the first lock member and the second lock member are always arranged so as to be operable on the outer surface of the electronic device, even if a double lock is applied, the operation is always inadvertent. There is no denying that they are at risk. In such a situation, no matter how much the lid lock is strengthened, it is not sufficient to prevent erroneous operation.

  Therefore, the present invention provides a technique that can more reliably prevent erroneous operations.

  In order to solve the above problems, the present invention employs the following solutions.

First, the present invention provides an operation error prevention device.
The erroneous operation preventing apparatus has a configuration including a “lid”, a “lock mechanism”, and a “release mechanism”. Among these, the “lid” can be displaced between the closed position and the open position, but shields the operation unit at the closed position. Accordingly, the operation unit is not exposed in a state where the “lid” is in the closed position, and it is possible to reliably prevent an erroneous operation during that time.

  The shielding of the operation unit by the “lid” is made stronger by the “lock mechanism”. That is, the “lock mechanism” regulates that the “lid” is displaced toward the open position when the “lid” is in the closed position. Therefore, while the “lid” is in the closed position, an erroneous operation on the operation unit cannot occur unless the restriction by the “lock mechanism” is released.

  The restriction by the “lock mechanism” can be released by the “release mechanism”. That is, the “release mechanism” can release the restriction on the displacement of the “lid” by the “lock mechanism” only when two operations are received simultaneously. At this time, since the two operations on the “release mechanism” are operations in different directions of “first direction” and “second direction”, only by receiving an operation in any one direction, “ The restriction by the “lock mechanism” is not released.

  In addition, the “release mechanism” does not release the restriction on the displacement of the lid by the “lock mechanism” unless two operations with different directions are simultaneously received. Therefore, even if the two operations are received separately, the restriction of the displacement of the lid by the “lock mechanism” alone is not released. Even if the two operations are received before and after the time, the “lock mechanism” The restriction on the displacement of the lid by "" is not released. Thereby, prevention of the erroneous operation with respect to an operation part is further strengthened.

  In the present invention, the “release mechanism” is a “lock mechanism” only when it receives an operation in the second direction while being subjected to an operation in the first direction. A mode in which the restriction on the displacement of the lid can be released is preferable.

If it is said aspect, there will be operation in a 2nd direction previously, and the operation in a 1st direction will be added there, and it will be "it received two operations simultaneously" for the first time. In this case, when the operation unit is operated for a legitimate purpose while preventing an erroneous operation, it is not necessary to start two operations at once, so that the convenience during operation can be improved.

  The “release mechanism” may include an “urging member”. The “biasing member” is a member that generates a resistance against an operation in at least one of the first direction and the second direction with respect to two operations received by the “release mechanism”.

  If it is said aspect, even if operation in one direction is performed carelessly (unconsciously by the user), the operation can be canceled by the drag of the “biasing member”. Thereby, the restriction | limiting by a "lock mechanism" is not cancelled | released carelessly and the erroneous operation with respect to an operation part can be prevented more reliably.

  The “release mechanism” may include an “release member” and a “restraining member”. Among these, when the operation in the first direction is received, the “release member” is displaced from the initial position where the restriction by the “lock mechanism” is effective to the release position, and the restriction is released. The “stop member” prevents the “release member” from displacing from the initial position to the release position while the operation in the second direction is not being performed. The “release member” is allowed to be displaced.

  In this case, normally, if the “release member” is displaced from the initial position to the release position by an operation in the first direction, the restriction by the “lock mechanism” is released, but the displacement by the “release member” is “stopped”. It is restrained by “members”. For this reason, in order to release the restriction by the “lock mechanism”, the restriction by the “restraining member” must be released by the operation in the second direction, and in the meantime (at the same time as the operation in the second direction). ) It is necessary to move the “release member” from the initial position to the release position by performing an operation in the first direction. Thereby, since the “lid” is not inadvertently displaced to the open position, it is possible to reliably prevent an erroneous operation on the operation unit.

Secondly, the present invention provides an electronic apparatus.
The electronic apparatus according to the present invention includes a main body that houses the operation unit, and prevents the operation unit from being erroneously operated when the main unit is used by using the above-described erroneous operation prevention device.

  According to the electronic apparatus of the present invention, since the operation unit is not exposed to the outside of the main body during use, an erroneous operation is basically unlikely to occur. Furthermore, since the exposure of the operation unit is suppressed by the erroneous operation preventing device, it is possible to reliably prevent erroneous operation.

  According to the present invention, erroneous operations can be prevented more reliably.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a hand microphone is cited as an example of an electronic device to which an erroneous operation prevention device is applied, but the electronic device of the present invention is not limited to this example.

  FIG. 1 is a perspective view showing a hand microphone 100 which is an example of an electronic apparatus using an erroneous operation preventing device. The hand microphone 100 is a wireless microphone that wirelessly communicates with an acoustic facility (not shown) using a specific frequency band and transmits an audio signal, for example.

  The hand microphone 100 is roughly composed of a main body 102 and a microphone head 104. The main body 102 has a substantially cylindrical shape, and its outer diameter and length are set such that a user such as a presenter or a performer can easily hold it with one hand. The microphone head 104 has a windshield 110 having a substantially spherical shape at the tip, and the whole is connected to one end (upper end) of the main body 102 via a neck 111. Although not particularly shown, the microphone head 104 has a built-in microphone, and the main body 102 has a built-in circuit board on which electronic components are mounted.

  In addition, a battery 106 is attached to the main body 102. The battery 106 is detachable, and forms an outer surface together with the main body 102 when mounted. An antenna 108 is formed at the other end (lower end) of the main body 102.

[Incorrect operation prevention device]
The hand microphone 100 shown in FIG. 1 is not provided with any operation unit such as a switch at an exposed position on the outer surface thereof. That is, the switch cover 120 is provided at the other end (lower end) of the main body 102, and the switches of the hand microphone 100 are usually shielded by the switch cover 120. The switch cover 120 has two hinges 122 and is supported by the main body 102 via the hinges 122 so as to be openable and closable. As long as the switch cover 120 is not opened, the operation unit is not operated by mistake. In addition, the hand microphone 100 is usually designed on the assumption that the user holds the upper part of the main body 102 (the position of the battery 106 in the longitudinal direction), and the switch cover 120 is positioned at the lower end of the main body 102. Therefore, the user does not touch the vicinity of the switch cover 120 during the performance / lecture, thereby preventing the switch cover 120 from being inadvertently opened.

  The switch cover 120 is provided with a slide knob 124. When the slide knob 124 is slid, the lock is released and the switch cover 120 can be opened. When the switch cover 120 is opened, the operation unit built in the main body 102 is exposed, and various operations (for example, power ON / OFF, channel setting, microphone characteristic setting, sensitivity setting, removal of the battery 106, etc.) are possible only there. However, it is not the user presenter or performer who performs such an operation, but an acoustic engineer (so-called staff). However, in this embodiment, even if the user touches the slide knob 124 unintentionally, a structure is employed in which the lock is not inadvertently released. That is, the slide knob 124 is provided with a relatively small lock component 126, and the slide knob 124 cannot be operated unless the lock component 126 is operated. The switch cover 120 has a built-in mechanical component to be locked, but the mechanical component is covered with a pressing plate 128. Hereinafter, the configuration of the operation error prevention device will be described in more detail.

[Lid]
The switch cover 120 has a tongue-like shape extending in the longitudinal direction of the main body 102 and is supported (connected) to the main body 102 via the two hinges 122 as described above. In the present embodiment, since the hinge 122 is located on the lower end side of the main body 102, when the switch cover 120 is opened with the hand microphone 100 in the upright state, the body 102 looks like a drawbridge. However, the opening / closing direction of the switch cover 120 is not limited to this example, and may be opened / closed on the opposite side of the longitudinal direction or may be opened / closed in the width direction. Alternatively, the switch cover 120 may be slidably opened / closed with respect to the main body 102 or may be detachably opened / closed.

[Lock mechanism]
FIG. 2 is a cross-sectional view (a cross-sectional view taken along the line II-II in FIG. 1) showing the lock mechanism of the switch cover 120. Here, FIG. 2A shows a state where the switch cover 120 is locked, and FIG. 2B shows a state where the lock is released.

[Locked state]
In FIG. 2, (A): The switch cover 120 includes a pair of latch parts 130 and 132 in the width direction, and these latch parts 130 and 132 are arranged with a coil spring 134 interposed therebetween. . The coil spring 134 is a compression spring. In the locked state shown in FIG. 2A, the coil spring 134 pushes the pair of latch parts 130 and 132 outward in the width direction of the switch cover 120 by the repulsive force. Yes. The pair of latch parts 130 and 132 have lock claws 130 a and 132 a, respectively, and these lock claws 130 a and 132 a extend toward both outer sides in the width direction of the switch cover 120. On the other hand, through holes 120b are formed at both side edges of the switch cover 120 as viewed in the width direction, and these through holes 120b are large enough to allow the corresponding lock claws 130a and 132a to be slidably inserted. And has a shape.

  As described above, when the coil spring 134 pushes out the pair of latch parts 130 and 132, the lock claws 130a and 132a protrude from the both side surfaces of the switch cover 120 through the through holes 120b. On the other hand, the exterior cover 102a constituting the outer shell of the main body 102 is formed with an opening corresponding to the switch cover 120 (without reference numeral). The opening has a size that can accept the outer shape of the switch cover 120 and It has a shape. The outer cover 102a is formed with a latching portion 102b at a position corresponding to each of the pair of lock claws 130a and 132a, and the latching portion 102b is formed so that the edge of the opening is stepped. It is formed inside.

  As described above, when the switch cover 120 is in the closed state (closed position), the tip ends of the pair of lock claws 130a and 132a are hooked on the hook portion 102b, and the switch cover 120 is locked with respect to the main body 102. It becomes a state. In this state, the switch cover 120 is not opened, and an operation with respect to an operation unit (not shown) housed in the main body 102 is impossible.

[Unlocked state]
In FIG. 2, (B): A pair of latch parts 130 and 132 are pulled into the inside (center side) of the switch cover 120 against the repulsive force of the coil spring 134, and the lock claws 130a and 132a and the latching portion 102b When the catch is eliminated, the switch cover 120 is unlocked. In this unlocked state, the switch cover 120 is pushed in the opening direction by a leaf spring (not shown) to facilitate the opening. Thereby, since the operation part accommodated in the main body 102 is exposed, various operations can be performed for a regular purpose. For convenience of illustration, the coil spring 134 is shown in an uncompressed state, but in actuality, the coil spring 134 is in a compressed state as much as the pair of latch parts 130 and 132 are retracted.

FIG. 3 is a perspective view showing an open state of the switch cover 120.
In FIG. 3, (A): As described above, the switch cover 120 can be opened in the unlocked state. Further, as the switch cover 120 is opened, the switch module 150 is exposed here as the operation unit accommodated in the main body 102. When the switch cover 120 is opened, the pair of latch parts 130 and 132 are pushed out to both outer sides of the switch cover 120 by the repulsive force of the coil spring 134, and the pair of lock claws 130a and 132a protrude from both side surfaces. Become.

(Operation section)
Here, in the switch module 150, for example, a power switch 152, a toggle switch 154, an LCD panel 156, and the like are integrated. The power switch 152 turns on / off the power of the hand microphone 100, and the toggle switch 154 changes various settings of the hand microphone 100. Further, while the power is on, the remaining amount of the battery 106, status of various settings, and the like are displayed on the LCD panel 156.

  In addition to the switch module 150, a battery claw 158 is accommodated in the main body 102, and this battery claw 158 is operated by a staff member when removing the battery 106 from the main body 102. The battery pawl 158 is also exposed by opening the switch cover 120 and can be operated. In other words, since the battery 106 cannot be removed from the hand microphone 100 unless the switch cover 120 is opened, the battery 106 is not accidentally dropped during use, and the hand microphone 100 is not disabled.

  3B: The switch cover 120 can be arbitrarily opened within a movable range by the hinge 122. FIG. That is, in a state where the switch cover 120 is largely opened, the switch cover 120 does not overlap even part of the opening surface of the main body 102, so that the operation on the switch module 150, the battery pawl 158, and the like becomes easier. In addition, the main body 102 accommodates a USB port 160 (connection interface). With the switch cover 120 opened, a cable is connected to the USB port 160 to supply power to the battery 106 from a PC or the like. Serial communication with the built-in electronic circuit becomes possible.

  The leaf spring 123 described above is provided on the main body 102 between the two hinges 122. When the lock state is released, the switch cover 120 is lifted in the opening direction by a certain angle by the restoring force of the leaf spring 123. . When the switch cover 120 is closed again, when the switch cover 120 is pushed to the closed position against the restoring force of the leaf spring 123, the pair of lock claws 130a and 132a are hooked on the hooking portion 102b and the switch cover 120 is moved. Lock it.

[Release mechanism]
Here, FIG. 3B shows the back shape of the lock component 126 described above together with the back surface of the switch cover 120. The lock component 126 is operated on the front side of the switch cover 120, and the lock component 126 uses the structure on the back side to lock and release the slide knob 124. In addition, an L-shaped hole 120a is formed on the back surface of the switch cover 120 to lock and unlock the lock member 126. Hereinafter, the lock component 126 and the L-shaped hole 120a will be described in more detail. In addition, a configuration for locking and releasing the latch parts 130 and 132 by the slide knob 124 will be described.

  FIG. 4 is a front view showing the switch cover 120 alone. In the drawing, the pressing plate 128 is removed from the switch cover 120 (the same applies to the following).

[Release member]
The slide knob 124 is supported with respect to the switch cover 120 so as to be slidable within a certain range in the longitudinal direction (vertical direction as viewed in FIG. 4). The slide knob 124 in the switch cover 120 is disposed in the longitudinal direction so as to form a T shape with respect to the pair of latch parts 130 and 132 in the width direction. Further, the slide knob 124 is provided with irregularities on its outer surface, so that the operator can catch the operator's finger to facilitate the slide operation.

  As described above, the latch components 130 and 132 and the coil spring 134 are usually covered with the pressing plate 128, but the slide knob 124 also has one end portion in the longitudinal direction (the upper end portion in FIG. 4) at the pressing plate. 128 is covered. That is, a V-shaped guide edge 124 a is formed at one end of the slide knob 124, and the guide edge 124 a is widened in the sliding direction (upward direction) of the slide knob 124. The slide knob 124 is mechanically connected to the pair of latch parts 130 and 132 at the guide edge 124 a, so that one end is covered with the pressing plate 128.

  On the other hand, the claw portions 130b and 132b are formed on the pair of latch parts 130 and 132, respectively, at portions where they are opposed to each other. The claw portions 130b and 132b are formed so that the end edges of the slide knob 124 facing the guide edge 124a are diagonally aligned with the V-shape of the guide edge 124a. The pair of latch components 130 and 132 are in contact with the guide edge 124a of the slide knob 124 at the oblique end edges of the claw portions 130b and 132b, respectively, and are mechanically connected to each other in this state.

〔Initial position〕
In the initial position shown in FIG. 4, the slide knob 124 is farthest from the latch parts 130 and 132, and in this initial position, the slide knob 124 effectively functions to lock the switch cover 120 by the latch parts 130 and 132. Yes. This is because, when the slide knob 124 is in the initial position, the claw portions 130b and 132b that contact the diverging guide edge 124a are separated to the farthest position from each other. The switch cover 120 can be locked by protruding outward from both side surfaces of the 120.

[Release position]
Although not shown in FIG. 4, when the slide knob 124 is slid in the direction (first direction) to approach the pair of latch parts 130 and 132 from this state, the claws are formed along the V-shaped guide edge 124 a. As a result of the portions 130b and 132b being guided relatively inward (valley side), the pair of latch parts 130 and 132 move toward each other, and the lock claws 130a and 132a are located in the switch cover 120 (through hole 120b). Will be drawn into. As a result, the lock of the switch cover 120 is released, but in this embodiment, only the slide knob 124 cannot be slid by itself, and if the lock part 126 is not operated at the same time, the switch cover The structure in which the lock 120 is not released is adopted.

(Stopping member)
The lock component 126 is smaller than the slide knob 124. That is, the lock component 126 has a rectangular shape in a front view shown in FIG. 4, but the length of one side thereof is about half or less of the width of the slide knob 124. The lock part 126 is supported so as to be slidable within a certain range in the width direction with respect to the slide knob 124 in a state where most of the lock part 126 is hidden behind the slide knob 124. Conversely, the lock component 126 is restrained from sliding in the other direction (for example, the longitudinal direction) with respect to the slide knob 124. A groove 120c is formed on the front surface of the slide knob 124, and a part of the lock component 126 protrudes to the front side through the groove 120c. Therefore, the lock component 126 can be slid in the width direction (second direction) of the slide knob 124 by operating the protruding portion on the front side of the slide knob 124. When the slide knob 124 is slid in the longitudinal direction of the switch cover 120, the lock component 126 also moves in the longitudinal direction together with the slide knob 124. This is the direction in which the lock component 126 itself is operated. Absent.

[Biasing member (momentary operation)]
As described above, the lock component 126 can be slid in the width direction of the slide knob 124. At this time, a structure (momentary operation) that generates a certain amount of drag is employed. Specifically, a torsion spring 136 is disposed on the back side of the slide knob 124, and the torsion spring 136 presses the lock component 126 to one side end side in the width direction of the slide knob 124 with its restoring force. Yes. Therefore, as shown in FIG. 4, the lock component 126 is normally held at a position where the protruding portion is in contact with one end of the groove 120 c.

  FIG. 5 is a partial rear view of the switch cover 120 showing a state in which the displacement of the slide knob 124 by the lock component 126 is restrained. As described above, the L-shaped hole 120 a is formed on the back surface of the switch cover 120. The L-shaped hole 120a is substantially L-shaped when the switch cover 120 is viewed from the back, but the inner portion of the L-shape is obliquely chamfered (cut). The lock part 126 has a portion protruding into the L-shaped hole 120a on the back side, and as described above, the portion where the lock part 126 protrudes into the groove 120c on the front side by the torsion spring 136 is at one end. In the state of being held at the contact position, the protruding portion is in contact with one end even in the L-shaped hole 120a. In this state, the lock part 126 can move in the L-shaped hole 120a in the width direction of the switch cover 120, but it can be seen that the movement in the longitudinal direction is restricted.

[Sliding knob control]
Therefore, even if only the slide knob 124 is slid in the state where the lock component 126 is not operated, the lock component 126 cannot move in the longitudinal direction in the L-shaped hole 120a on the back side, and as a result Therefore, the displacement of the slide knob 124 is restrained.

[Operation of lock parts]
FIG. 6 is a front view of the switch cover 120 showing how the lock part 126 is operated. When the entire lock part 126 is slid in the width direction (second direction) of the slide knob 124 through the portion protruding into the groove 120c of the lock part 126, the lock part 126 has been held by the torsion spring 136 until then. Move from position to opposite side. At this time, since the torsional force acts on the torsion spring 136, the torsion spring 136 can generate a resistance against the sliding operation of the lock component 126. Therefore, when the force is released only by temporarily sliding the lock component 126 (the operation is stopped), the lock component 126 is returned to the original position (FIGS. 4 and 5) by the drag of the torsion spring 136. Become.

  FIG. 7 is a partial rear view of the switch cover 120 showing a state in which the displacement of the slide knob 124 is allowed. As described above, when the lock component 126 is subjected to the slide operation and the operation is held, a portion where the lock component 126 protrudes in the L-shaped hole 120a is separated from one end. Thus, the lock component 126 has been allowed to move only in the width direction in the L-shaped hole 120a until now (FIG. 5), but this time, the lock component 126 is also allowed to move in the longitudinal direction in the L-shaped hole 120a. It turns out that it will be in a state. However, when the lock component 126 is temporarily slid and the force is released (the operation is stopped), the lock component 126 is returned to the original position (FIG. 5) by the drag of the torsion spring 136, and again. Movement in the longitudinal direction is restricted.

〔unlock〕
FIG. 8 is a front view showing a state where the lock of the switch cover 120 is actually released. As described above, while the lock component 126 is slid in the width direction (second direction) and the operation is maintained, the slide knob 124 is slid in the longitudinal direction (first direction). Can do. In this way, in addition to the slide operation in the width direction with respect to the lock component 126, the slide operation in the longitudinal direction with respect to the slide knob 124 is performed thereover, and when two operations are performed simultaneously, the lock of the switch cover 120 is locked. Can be released. Specifically, the claw portions 130b and 132b are moved along the V-shaped guide edge 124a when the slide knob 124 is slid in the direction in which the slide knob 124 approaches the pair of latch parts 130 and 132 (first direction). As a result of being guided relatively inward (valley side), the pair of latch parts 130 and 132 move in a direction approaching each other, and the lock claws 130a and 132a are pulled into the switch cover 120 (through hole 120b). Become. As a result, the lock of the switch cover 120 with respect to the main body 102 is released.

  FIG. 9 is a partial rear view of the switch cover 120 showing a state in which the slide knob 124 is displaced. As described above, when the lock component 126 receives a slide operation and the slide knob 124 is slid while the operation is held, the protruding portion of the lock component 126 moves in the longitudinal direction within the L-shaped hole 120a. To do. Even if the operation on the lock component 126 is lost in this state, the unlocking of the switch cover 120 remains valid because the slide knob 124 has already been displaced from the initial position to the release position (FIG. 8).

  Thereafter, when there is no operation on the slide knob 124 with the switch cover 120 opened, the pair of latch parts 130 and 132 are moved away from each other by the repulsive force of the coil spring 134. Accordingly, the pair of latch parts 130 and 132 relatively push back the slide knob 124 via the claw portions 130b and 132b, respectively. As a result, the slide knob 124 returns to the initial position. At this time, the lock component 126 also returns to the original position (FIGS. 4 and 5) due to the repulsive force of the torsion spring 136, so that the movement of the slide knob 124 is restrained unless the lock component 126 is operated thereafter. Become.

According to the above-described embodiment, the following utility is obtained.
The switch cover 120 cannot be unlocked only by sliding the slide knob 124, and the switch cover 120 is operated in two directions after operating the lock component 126 in a direction (orthogonal direction) different from the operation of the slide knob 124. If not performed at the same time, the lock is not released. Therefore, even if the presenter or performer unintentionally touches the slide knob 124 while using the hand microphone 100, the switch cover 120 is not inadvertently unlocked. Thereby, it is possible to reliably prevent an erroneous operation on the operation unit (the switch module 150 or the like) and to eliminate accidents during use (disappearance of sound, etc.)

  Further, the slide knob 124 cannot be slid only by temporarily operating the lock component 126, and in order to operate the slide knob 124, it is necessary to maintain (continue) the operation of the lock component 126. is there. Thereby, it is possible to prevent the switch cover 120 from being unlocked by simply performing two operations in sequence, and it is possible to eliminate erroneous operations more reliably.

  In addition, the lock component 126 itself is difficult to operate, and thus it is difficult to unlock the slide knob 124. That is, the part where the presenter / actor etc. can easily hold the hand microphone 100 is the part where the battery 106 of the main body 102 is attached, and the switch cover 120 located at the lower part of the main body 102 is not usually touched. By disposing the lock component 126 on the lower end side of the switch cover 120 as much as possible, the operation is made more difficult. Accordingly, the lock component 126 is not inadvertently touched during use, and erroneous operation can be further prevented.

  The present invention can be implemented with various modifications without being limited to the above-described embodiment. For example, the operation directions of the slide knob 124 and the lock component 126 may be opposite to each other. Further, even if the operation with respect to the slide knob 124 is the slide direction, the operation with respect to the lock component 126 may be the pushing direction, the pulling direction, the rotating direction, or the like, or the slide knob 124 itself may be an operation other than the slide.

  In one embodiment, an example of an electronic device is the hand microphone 100, but the electronic device may be a portable information terminal, a personal computer, a tablet terminal, a digital camera, or the like.

  In addition, the form of the hand microphone 100 and the structure of each part given together with the drawings are just preferable examples, and the present invention can be suitably implemented even if various elements are added to the basic structure or a part thereof is replaced. Needless to say.
